For wellbutrin XL at least, the name brand's sustained release mechanism is a bunch of complicated polymer substances made by a company in Germany.
I can't remember the company's name, but I looked at their site and it looks like they put a lot of work into making this mechanism.
I could see how a generic could not get that right.
But it is puzzling when non-SR/XL/CR/XR generic drugs are less efficacious. Do the generic makers like Teva cut corners or have poor yields? Is there some sort of collusion to purposely make the generics less effective to protect sales of the original?
It seems like generics should have to go through some sort of clinical trial to make sure they actually work as advertised. Of course, this will make them more expensive.
